基于小型飞机综合航电系统的应用需求,通过分析小型综合座舱电子系统组成结构,设计了系统逻辑架构,给出了飞行显示器与综合处理机的顶层功能流框图。提出了多通道数据的实时采集、冗余路径实现、数据加卸载等3项关键技术,给出了具体的设计实现方法。该系统在VxWorks嵌入式实时操作系统上实现,已在海鸥300飞机综合航电系统项目中安装使用。
Based on the application requirements of small aircraft integrated avionics system, by analyzing the composition of small integrated cockpit electronic system, the system logical structure is designed and the top functional flow chart of the flight display and the integrated processor is given. The key technologies of real-time acquisition of multi-channel data, implementation of redundant paths and data unloading are put forward, and the specific design and implementation methods are given. The system is implemented on the VxWorks embedded real-time operating system and has been installed and used in the Seagull 300 Integrated Avionics System Project.
